Sparkling Waters 1 Huckit Beach Resort

Star Coin 1 - The first star coin is located inside the second hut in the level, which is the first hut you pass through moving right.

Star Coin 2 - When you get to the area with the army of Huckits and water geyers, look for a green pipe at the bottom. Dodge the rocks being hurled and enter the pipe to find a giant 8-bit Luigi along with the Star Coin.

Star Coin 3 - The final Star Coin is hidden from sight. When you reach the are with two multi tiered platforms with Huckits on each side, head to the right side. The Huckits are seperated by breakable blocks, so ground pound all the way through. As you take them out and descend, a Star Coin will emerge.
